It comes with 3 different sizes of rods to adjust the length 5.3" / 6.5" / 10.5".
I opted for the 10.5 as I was tired of the reduced FM reception with the carbon fiber stubby. http://www.stubbyantenna.com/y-serie...stubby-antenna
Only one caveat with this model, it's not made to fit the Ram! If it wasn't for the adapter I had off the sickspeed carbon stubby it wouldn't fit. Love the look and my FM reception is right back to where it was with the factory antenna.
